WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 643,437, dated February 13, 1900. Application filed November 16,1899. Serial No. 737,207. (No model.)

To aZZ whom it may concern:

Be it known that I, SEPTIMUS TAYLOR WIL- LIAMS, residing at Dyersburg, in the county of Dyer and State of Tennessee, have made certain new and useful Improvements in Wagon-Brakes, of which the following is a specification.

' Myinvention is an improvement in brakes adapted for farm and other heavy wagons. It is more particularly an improvement in that class of such brakes in which a brakebar is arranged and adapted to rotate upon its own axis and is connected with a fixed part of the wagon-frame by a rope or chain in such manner that upon rotation of the bar the chain is taken up by winding upon itand the bar thereby brought in contact with the wheels.

My invention relates particularly to means for suspending and guiding the roller brakebar, as hereinafter described.

In the accompanying drawings, Figure l is a perspective view of the rear portion of a wagon-gear provided with myimproved brake. Fig. 2 is a section (see line 2 2, Fig. 1) showing the brake-bar applied to the wheels as required for braking. Fig. 3 is a similar View showing the brake-bar thrown off the wheels. Fig. 4 is a plan view showingthe parts in the position illustrated in Fig. 1. r

a indicates the reach or coupling-pole, b the rear hounds, c the rear axle, and d the rear wheels, of the wagon-gear.

The roller brake-bar 1 is suspended in front of the wheels (1 by means of curved orarcshaped loops 2, which are formed of small iron rods curved to the required shape and rigidly connected with the brake-bar. Supports for such loops or guides are provided by means of an iron bar .3, which extends across the reach and hounds at a point just in front of the forward portion of the wheels d and whose bent or dropped ends project through the said loops, as shown in Fig. 1. The said bar 3 is held immovable by suitable fastening devices. the axle c and also to the brake-bar l in such manner that when the brake-bar is rotated the chain is taken up by being wound thereon, as shown in Fig. 2. A long iron brake lever 5 is rigidly attached to one end of the A chain 4 is attached tobrake-bar l and in its normal position extends rearward at an angle of about forty-five degrees. The weight of the lever 5 suffices when in this position to hold the brake-bar 1 away from or out of contact with the wheels (1, as shown in Fig. 3, the ends of the brakesupporting'rod 3 being then at the upper ends of the loops 2. The loops thus serve to hold the brake-bar l away from the wheels and prevent accidental application of the brake. When the brake-lever 5 is raised to a vertical position, or thereabout, as shown in Fig.

2, the brake-bar 1, being rotated upon its axis, takes up or shortens the chain 4 and is thus drawn backward against the wheels 61, as shown in Fig. 2, thus efiectively braking the same. In this operation the loops 2 ride on the ends of bar 3, and thus guide as well as support the brake-bar in its movement.

Thus constructed and adapted to operate my improved brake is simple, durable, effective, and easily operated.

- It is obvious that a wire or hempen rope may be substituted for the chain 4. It is also apparent that a rod may be connected with the brake-lever 5, as shown in Fig. 1, and extended forward into suitable position for attachment to a hand-lever (not shown) which may be conveniently operated by the driver.

What I claim is- 1. In a wagon-brake of the class specified,

the combination, with the reach and wheels,

of a rotatable brake-bar, a chain, or equivalent,attached thereto and to the wagon-frame, a lever attached to the brake-bar, for use in rotating it, and adapted, when thrown down,

to rotate it in the direction required for rewinding the chain, and rigid devices attached to the brake-bar and coacting with fixed parts on the frame, to automatically throw the brake-bar away from the wheels when the lever is lowered, substantially as shown and described.

2. In a wagon-brake of the class specified, the combination, with the reach and wheels, of a rotatable brake-bar, a chain or equivalent connecting the same with the rear axle, curved or arc-shaped, rigid guide-loops attached to the brake-bar, fixed lateral projections on the frame upon which the said loops are supported and guided, and a brake lever attached to the bar for rotating it, snbstalr therefrom for sliding engagement with the tially as shown and described. ends of the fixed bar, a chain, and an operat- 1o 3.
